help with unit conversions

Question

.00012 s to ns 

please explain and show work

Answer 1

Hello Hannah,

 

I am assuming "ns" means nanoseconds. The "nano" prefix (stolen by apple not long ago!) means one billionth:

 

1 ns = 0.0000000001 s = 1 x 10^-9  seconds.

 

Converting seconds to nanoseconds can be easily done by multiplying by 1 billion = 10⁹ .

 

0.00012 s * 10⁹ nanoseconds/second = 120,000 nanoseconds.

 

I hope that helps.
